IMPROVEMENT IN HEATING APPARATUS FOR SLEIGHS AND CARRIAGES.

Specil'i :at-ion forming part of Letters Patent No. 1&9,522, dated April7, 1874; application led To all whom t may concern Be it known that we,THoMAs H. PRICE and THEoDoEE F. WADE, of La Fayette, in the county ofTippecanoe and State of Indiana, have invented a new and ImprovedHeating Attachment for Sleighs, Oarriag'es, die.; and We do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawing forming a partof this specification, in which- Figure 1 is a partly-sectionalelevation of a sleigh with our improved heating apparatusattached. Fig.2 is a cross section of the heating apparatus proper. Fig. 3 is a planview, reduced, and part broken out, of the apparatus and a fragment ofthe sleigh-bottom.

The invention is an improvement in heating or,foot\varming attachmentsfor Vsleighs; and relates to an air-heating box and a perforated casecontaining it, the same being applied to a sleigh-bottom in connectionWith a reservoir and burners for containing and consuming a suitableliquid hydrocarbon, as hereinafter fully described.

In the drawing, a metal case, A, preferably of semi-cylindrical form,and having perforated sides for admission of air, is applied to thebottom of the sleigh-body C, directly beneath the slot or openingtherein, and secured by means of screws or other suitable devices.Burners D are arranged within this case, and the burning-Huid isconducted to them by a tube leading from a reservoir, E, located beneaththe seat, or elsewhere about the sleigh, it being only necessary that itbe above the burners, in order 'to cause the iiuid to feed properly. Toregulate the feed, a stop-cock7 F, is provided in the tube G, as shown.

For producing the best effect, We prefer to employ a volatilehydrocarbon liquid to supply the burners, which are constructed in sucha manner as to vaporize the same, and thus prevent `formation or escapeof smoke.

The upper side of the case A is formed by the concave bottom of acast-metal box, H, which is supported by horizontal flanges, as shown.The object of making the bottom concave is to give more heating-surfaceand more space in box H, to prevent the sides of the box becoming toohot, and to coniine the smoke (which forms when the burners are ig-February 17, 1874.

nited) from passing upward. The cover ofthe box is a perforated plate,I, having vertical anges to retain it in place, and forming, by itsarrangement, a part of the concave bottom of the sleigh-body.

In practice, the bottom of the box H becomes unduly heated along themiddle, and too little at other points. rlo'obviate this difiiculty, wearrange a bar, K, longitudinally beneath the center of the concave, yandattach it to the ends of the box. `It is requisite that the bar be of aquality to conduct heat with considerable facility, and for this reasoncopper or analogous material is preferable; but it may be cast in onepiece with the box H.

By the arrangement above described, the

cock F being' turned, the oil flows to the burners, Where it is ignited,and causes the concave bottom and adjacent or connected parts of box Hto become heated. This in turn heats the air contained in it, whichnaturally escapes upward in contact with the feet and limbs of thoseoccupying the sleigh. The fresh or colder air which enters the box issubjected to a like heat, and thus a constant and ascending current ofhot air is established and maintained.

If the degree of heat be at any time too great, it may be readilylessened by turning the stop-cock, and thus diminishing the quantity ofoil supplied to the burners.

If the apparatus be attached to a carriage, for use in the winterseason, all its parts may be detached to adapt the carriage for summeruse, save the perforated top ofthe box H, which will close the openingin the bottom.

Having thus described our invention, what we claim is-d The case A,having a flanged top and perforated sides, and the air-heating box H,haviu g perforated cover-I and concave bottom traversed by the bar K,said parts being combined and applied to the sleigh-bottom, as shown anddescribed.
